Not to be outdone by Porsche, Cadillac will offer its own special edition CTS-Vs later this year dubbed the "Black Diamond" series, featuring blacked-out everything and paint that if you stare at long enough, looks like it was worth the extra $4,850.

The first person to pit a 911 Black Series versus a CTS-V Coupe Black Diamond edition wins a bag of coal dust, a sleep mask and a Blu-Ray copy of "Coffy."
